Application filed May 8, 1914. Serial No. 837,237.

To all whom it may concern:

Be it known that I, VVILLIAM M. DALTON, a citizen of the United States, residing at America, in the county of Walker, State of Alabama, have invented certain new and useful Improvements in \Vire-Stretchers; and 1 do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in wire stretchers.

The principal object of the invention is to provide novel means for shifting the movable wire pulling portion of the device, and to provide novel means for insuring the positive grip of said means.

Uther objects and advantages will be apparent from the following description, when taken in connection with the accompanying drawings.

In the drawings: Figure 1 is an elevation of a wire stretcher made in accordance with my invention. Fig. 2' is an edge view there of. Fig. 3 is an elevation taken from the opposite side to that of Fig. 1. Fig. 4: is a longitudinal sectional view on the line 4.l of Fig. 1. Fig. 5 is a transverse sectional view on the line 5-5 of Fig. 2.

Referring particularly to the accompanying drawings, 10 represents a suitable plate which forms the base or support of the mechanism to be referred to later. Formed longitudinally of the plate is a slot 11. Arranged longitudinally on one face of the plate is a chain like device 12 formed of a plurality of strips of metal hinged together at 13 and formed with regularly spaced elongated slots 1 1. This slidable member is held in proper position on the plate by the guides 13. Pivotally mounted on an enlargement 15 at one end of the plate, and at the side opposite to the slotted member is a lever 16, and pivotally connected to this lever is a link 17 which extends longitudinally of the plate, the free end being formed with an arrow head 18, the shoulder of which moves within the slot of the plate, and is arranged to engage in the slots of the slotted stretching member. At the other end of the plate and on the same side as the lever 16 is mounted a spring latch or detent 19, the free end of which is formed with a beveled nose which extends through the slot of the plate and also engages in the slots of the slidable member. Secured to the side of the plate is a bar 20, the ends being mounted on bolts 21 and 22 and formed on the inner face near one end with a recess 23 to permit the free movement of the detent 19. The bolt 22 carries on the outer end a nut 2 1 which confines'a coiled spring 25 between it and the bar 20, and forces the bar yieldably against the link 17. One end of the sliding member carries a wire engaging clamp 26 while the other end of the plate 10 carries a loop 26 for attachment of a suitable chain 27 adapted to be secured around a post to anchor the plate.

It will thus be seen that when the lever 16 is moved in one direction, the nose of the link 17 will engage through one of the slots of the sliding member 12 and that by moving the lever in the opposite direction, the nose will engage the end wall of one of the slots and move the sliding member longitudinally on the plate. As the nose of the link 17 advances the operating member, the nose of the detent will engage successively in the slots and hold the member against sliding back so as to permit the link 17 to be moved back for engagement in another opening. Thus the sliding member can be moved to efiectively stretch a wire which is held in the clamp carried by said member. Particular attention is called to the spring pressed bar 20 which simultaneously holds the detent 19 and the link 17 in engagement with the slotted member 13. By turning the nut on the bolt 22, the tension of the spring can be regulated.

l/Vhat is claimed is:

A wire stretching device including a plate having a longitudinal slot formed therethrough, a lever pivotally mounted on the plate, a slotted member slidably mounted on the opposite side of the plate and opposite the said slotted plate, a link member pivotally connected to the lever and having a shouldered end disposed within the slot of the plate in position to engage in the slots of the sliding member, a detent extending through the slot of the plate and engaging successively in the slots of the sliding mem- In testimony whereof, I afiix my signaber, and a resiliently held bar mounted on ture in the presence of two Witnesses. the side of the plate and engaging With the WILLIAM M. DALTON. said link to hold the same in the slot of the Witnesses:

5 plate, said bar being formed With a recess J. AVARY ODAM,

to permit free movement of the detent. J OHN T. BOREMAN.
